RAILWAY TANK CAR.

"Application filed March 31, 1924. Serial No. 703,321. 2

objects to provide a cap thatcan be easily.

and quickly applied and removed under all ordinary conditions ofservice; to provide a cap that can be applied and removed withoutproducing a grinding action on the gasket between the cap and the tube;to provide fastening meansfor the cap that will permit the outlet to-loeopened without disconnecting the cap from the outlet tube or leg andthat will enable one toquickly and easily close the outlet underpressure of the lading; and to provide a gasket that will endure a longperiod of service and can be easily resurfaced Without specialequipment.

Further objects and advantages of the invention will become apparent asthe disclosure proceeds and the description is read in connection withthe accompanying drawings illustrating an embodiment of the inventionsuitable for application to existing cars, and in which Fig. 1 is afragmentary side elevation illustrating the lower portion of the outlettube or leg, with the cap in closed position;

Fig. 2 is a vertical section of the parts shown in Fig. 1;

Fig. 3 is a transverse section taken on the line 33 of Fig. 1;

Fig. 4; is a fragmentary view of the intermediate portion of a tank car;and

Fig. 5 is a fragmentary sectional 'view of the outlet tube and cap.

Referring to the drawings, 10 indicates the tank which is usuallyequipped with a dome 11 at the top near the middle; The bottom sheet 12of the tank is provided with an outlet 13 that communicates with anoutlet tube or leg 14 secured to the hottom sheet as shown at 15. In thecars now in general use the tube or leg is externally threaded at 16 toreceive a cap 17, which clamps a gasket between finished surfaces 18 and19 on the tube and cap to make a liquidrtight-joint. The outlet tubeisp'ro- 2 vided with a-valve seat20, and a valve head 21 cooperatestherewith to close the outlet. According to this invention, the cap 17is replaced bya cap 2&1 counterbored at 25' to receivethe threaded" endof the outlet .5

tube l l with convenientclearance. At'the bottom of the counterbore thecap is equipped with a soft metal, preferablyilead. gasket 26 forcontact with the endof the tube to make a tightseal. 3 The cap may beprovidedwith an.undercut groove 22 into which the gasket is fitted. Whenthe gasket is made of metal having a relative lowmelt= ing point itmaybe easily'formed by introducing the moltenmetalinto the cap andallowingit to :cool; The intermediate por-v tion of the cap isprovidedwithan opening 27 ofsmaller diameter than the tube-and athreaded plug 28 closing the opening.

The cap is equipped .withlugs 29 in suit- 'I able number projectinglaterally and. perforated to receive clamping bolts 30 for securing thecap in place. The upper ends of the bolts are in this instance supportedby an abutment flange 31 screwed'on to, the threaded end of the outlettube and locked by the check screw 32.

Preferably the perforations in the lugs 29 take the form of slots 33that' permit the so U bolts to be swung into positionwithout removingthe nuts. The ends of the lugs are provided with depending shoulders 34that cooperate with the nuts 35 to hold the bolts in place and preventtheir swinging laterally in the slots.

The perforations 36 in the flange 31 are preferably enlarged towards thebottom as indicated in Fig. 2, to permit the bolts to be swung tothedotted line position when the cap is to be remiovedand when a hose orthe like is to be threadedton to the tube.

The upper surface of thefiange 31 is pro vided with shoulders 37 tocooperate with T usually set up with 11,40" wrench, and the rotationcombined with the pressure on' the gasket results inan extremelydestructive grinding action that renders the life of the gasket 22 veryshort, and it oftenhappens I thattheoap leaks even when agasket isbe-'ingwus'ed-Ufor the-first time; The vfastening means for the cap 24involves noneof this destructive action, the gasket mgay, ens
